Univalent

 

a single, unpaired chromosome seen during the first division of meiosis. Normally, when gametes mature, homologous chromosomes with identical sets of genes pair during the prophase stage of meiosis and form bivalents. If pairing does not occur or if the bivalents diverge prematurely, univalents are formed.
